Handheld Nikon.  Nikon stabilizing lens.  Good hands, I’d say.

Third to last time I was out near Lake Powell, I was with Rodger (and about a dozen others) organizing hearings of the President’s Commission on Americans Outdoors.  We flew into Page, Arizona, on an Otter II coming up from Phoenix flying low, looking for elk, and legally buzzing Rainbow Bridge (impressive from the air, too).

We had a luncheon meeting at Wahweap Marina, as I recall; no time for boating.

Then we were off to the South Rim of the Grand Canyon.  There we inspected pine trees 30 feet tall, growing between the ties of the then-abandoned rail lines.  (And did a lot of other stuff.)

Today trains carry tourists to the South Rim on those tracks, the trees gone.  Progress, really.

Rodger carries on in the knowledge that use of the outdoors, especially these public lands, heals souls, and sometimes gives you great photos.

Rodger said I could borrow the photo.  Thanks!


NASA photo of the Moon, and Lincoln Memorial

January 21, 2014

This one NOT taken by the Hubble Space Telescope, though I suspect a telephoto lens was involved.

“An amazing photo of a full moon over the Lincoln Memorial.” Photo: NASA

Another photo from the Department of Interior’s Great American Outdoors Tumblr site.

It’s a rising Moon, with the photo taken from the west side of the Lincoln Memorial, perhaps from the Virginia side of the Potomac River.  The Lincoln Memorial is now part of the National Park Service’s portfolio of properties around our national capital.

Update: Jude Crook points out in comments (below) that this was a NASA Photo of the Day, originally; two federal agencies cooperating in the interest of photographic excellence . . .

Super Perigee Moon

The full moon is seen as it rises near the Lincoln Memorial, Saturday, March 19, 2011, in Washington. The full moon tonight is called a super perigee moon since it is at its closest to Earth in 2011. The last full moon so big and close to Earth occurred in March 1993.

September 12 — Anniversary of the 1962 day JFK challenged all of America to go to the Moon, “because it is hard”

September 12, 2013

Kennedy’s speech at Rice University, “We Choose to Go to the Moon,” was delivered in the football stadium (not nearly full), on September 12, 1962.

Obviously, that was back before global warming held such a tight death grip on Texas (it’s so bad here, even Rick Perry is trying to move north, out of the state).

Day in and day out, Kennedy’s speech, the text, the audio, and sources of commentary on it, are among the most popular of the nearly 5,000 posts at Millard Fillmore’s Bathtub. Go see why:

September 12, 1962, was also the ninth anniversary of JFK’s marriage to Jacqueline Bouvier.  She let him go out of town to talk rockets?

Anything for the nation, I suppose.

If the Moon were replaced by other planets, what would we see?

August 17, 2013

Odd and interesting idea for a video, from Yeti Animation:  What if the Moon disappeared, and were replaced by other planets in the solar system?  What would it look like?

I like the nonchalance with which the passing auto drivers and passengers treat these views.  Droll.

The ambitious filmmaker, YetPic1, describes the real science and non-science in the film:

Published on May 2, 2013

This is a visualization of what it might be like if the Moon was replaced with some of the other planets at the same distance as our moon. Planets Rendered in 4K resolution! On Change Quality click on “original” to view in 4k. You need a 4k Monitor to watch. otherwise just watch in 1080p or lower

SATURN!.. The super close moon is Dione, the one slightly further out is Tethys
Both are *tiny* but *very* close

In order show[n]:

Mars
Venus
Neptune
Uranus
Jupiter
Saturn

Mercury is intentionally left off as it isn’t Much bigger than our Moon (and hence is boring)

****************
on Jupiter, you might be able to make out the 4 big moons, They all have orbits larger than our moons orbit. but I stuck them on the far side of jupiter so that they could be seen so it looks as if they are closer (to Jupiter) than they really are.

***************
Video creation method
I created an Earth Moon system in 3dsmax, with accurate sizes and accurate orbital distances.. I than matched video of the real Moon with my video camera, against my model. I also researched the correct FOV of my video camera. I used both methods to verify my Virtual camera’s FOV (around 47 degrees). I next modeled up the rest of the planets in proper scale (Real values) set at the distance of the moon (center to center) (also real values), created the animation of them rotating around, and composited the whole bunch.
***************
Faq:

Scales used in Visualization:
Celestial Body Radius (in km)
Moon: 1738
Mars: 3397
Venus: 6052
Neptune: 25,269 (equatorial) 24,340 (polar)
Uranus: 25,559 (equatorial) 24,973 (polar)
Jupiter: 71,490 (equatorial) 66,854 (polar)
Saturn: 60,268 (equatorial) 54,360 (polar) (not including rings)

Distance to Moon 384,000km
Faq: (faq shrunk from other video for “reasons”)

1, We would not be engulfed by Jupiter or any other planet, Jupiter’s radius is 71,490 km and the distance to the Moon is 384,000km

2, We would suffer from really really horrible tides and earthquakes(and radiation)

3, I *did* model the Ring of debris around Uranus, I actually modeled 8 of them, but you can mostly just make out 3, This was actually the tipping point for me to render this out in 4k resolution

4, I love Pluto, and Mercury. They are left off because they are too small. Pluto is smaller than our Moon, and Mercury is not significantly larger than our Moon.

5, The “Sun” I used for lighting the planets is completely off from reality,

7 Orbiting! Yes! we would be a moon of Saturn, Jupiter, Uranus, and Neptune. They are much more massive than the Earth. Venus is about the same size of the Earth and we would orbit around a center point between us

8 Rotation rates and axial tilts are not accurate to anything

9 Radius of the Sun is 695,500 km, and hence if it were where our Moon is, we would be engulfed by it

10 Scales are Accurate, Every few days someone says my scales are wrong, Or that someone says I’m presenting Saturn as being bigger than Jupiter. I’m going to go through some of the arguments I keep hearing (paraphrasing each)

a. “You’re showing Saturn larger than Jupiter”: I am not, Saturn is clearly smaller than Jupiter in the video, Saturn+ring system *IS* larger than Jupiter (in terms of radius) This is easy to look up.

b. “Jupiter is 300 times larger than Earth! therefore it’s wrong in your video (or 1000 times larger etc)” : There are many sayings about how much larger Jupiter is than earth. 300 is Probably referring to Mass… 1000.. is probably referring to Volume. Without actually specifying the Dimension the argument is pretty moot. I will say this Jupiter’s Radius is about 11 times that of Earths, which fits precisely with my video.

c. “I saw another video where Jupiter Filled the sky!, therefore you’re wrong”: I am very familiar with the video. I even Like the video. However the FOV (field of view) of his Ground does not match the FOV of the planets. In other words, he has a wide angle lens on the ground, and a zoomed lens on the planets. To his own credit he admits this in his own description. In my video My ground FOV and my planet FOV are the same, and hence graphically matched and very reasonably accurate.

d. The confidence I have for my scales being correct is exceptionally high. The dimensions used for the planets and rings has at one point been triple checked along with the earth moon distance. It’s interesting to see how a *few* people have gotten completely worked up over their misconceptions on scale. The size of the Moon is a bit of an illusion, I Think if you still have misconceptions you should hold a dime out to arms length , and hold it against the moon, Or even go out with your own camera,, Zoom out all the way.. and take a photo of the Moon. It really is Tiny against the sky. It’s only about half a degree in angular diameter.

Thanks to everyone for watching, I enjoy making these

July 24 – Arrival Day: The journey’s not over until you get there

July 24, 2013

There’s a lot of encore material here — I think about this in the middle of the summer, and July 24 is a good day to commemorate arrivals: It’s Arrival Day.

July 24 – almost the end of the month, but not quite.  In Utah, July 24 is usually a state holiday, to celebrate the date in 1847 that the Mormon refugees arrived in Salt Lake Valley and began to set up their agriculture and schools.  In Salt Lake City, bands from across the state and floats from many entities form the “Days of ’47” Parade.  When I marched with the Pleasant Grove High School Viking Band, the route was  5 miles.  We had only one band uniform, for winter — I lost nearly 10 pounds carrying a Sousaphone.

When the Mormons got to Salt Lake, after a couple of months’ trekking across the plains (then known as “The Great American Desert,” the Great Basin and the Mojave being little known), and after being on the run for well over a year, they got right down to priorities.  Summer was nearly gone, and crops had to be planted quick.  Within a couple of weeks, the Mormons had dammed local streams to create irrigation systems to grow what they could before fall (this is, popularly, the first major crop irrigation set up in America); they’d started to lay out plans for settlements, with straight streets based on Cartesian-plane grids:  The first serious community planning?  And they began construction of schools, knowing education to be one of the most important attributes in the foundation of free societies, a position Mormons have reneged on recently in Utah.  Water, communities, schools.

Maybe spending a few weeks struggling across a prairie and risking your life focuses you on the important stuff.  How would it improve America if we put more people on a bus to Omaha, put them out there, and said, “Hike to Salt Lake City from here.”

They’d focus.  Can we start with Paul Ryan, John Boehner and Mitch McConnell?

Ah, the good old days!

July 24 features a number 0f other arrivals, too.

From various “Today in History” features, AP, New York Times, and others:

Buzz Aldrin walks on the moon, July 20, 1969

Buzz Aldrin walks on the moon, July 20, 1969 (Photo credit: Wikipedia)

July 24, 1969: Apollo 11 returned to the Earth, and splashed down in the Pacific Ocean, Michael Collins, Buzz Aldrin and Neil Armstrong — Aldrin and Armstrong having landed on the Moon.  In our celebrations of Apollo 11, and in our remembrances of President Kennedy, we may forget, though young kids rarely miss it, that Kennedy didn’t just say ‘Let’s put a guy on the Moon by 1970.’  Getting back safely was a key part of the challenge.

First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish

On July 24, 1969, the crew of Apollo 11 returned, safely.

July 24, 1847: A larger contingent of Mormons, refugees from a literal religious war in Illinois and Missouri, entered into the Salt Lake Valley under the leadership of Brigham Young, who famously said from his wagon sick-bed, “This is the place; drive on!”

Would there be a Mormon Tabernacle Choir, and organ, had the Mormons settled somewhere other than Utah? Wikipedia photo

July 24, 1866: Tennessee became the first of the Confederate States, the former “state in rebellion,” to be readmitted fully to the Union, following the end of the American Civil War. (Does Tennessee celebrate this anniversary in any way?)

July 24, 1911:  On July 24, 1911, American archeologist Hiram Bingham arrived at Machu Picchu in Peru.  We still don’t know all the reaons the Incas built that city on the top of very high mountains.  Cell service was not a factor.

July 24, 2005: Lance Armstrong won his seventh consecutive Tour de France bicycle race. Little did we know then, the journey wasn’t over. (Lance Armstrong is no relation to Neil Armstrong.  Did I need to point that out?)

English: Cropped image of Richard Nixon and Ni...

Nixon advance man William Safire claimed later than he’d set up the famous “debate” between Eisenhower’s Vice President Richard Nixon and Soviet Communist Party Premier Nikita Khrushchev, at the American National Exhibition in Moscow, 1959. Nixon argued that the technology on display made better the lives of average Americans, not just the wealthiest. (Photo credit: Wikipedia)

July 24, 1959: Visiting Moscow, USSR, to support an exhibit of U.S. technology and know-how, Vice President Richard Nixon engaged Soviet Communist Party Secretary and Premier Nikita Khruschev in a volley of points about which nation was doing better, at a display of the “typical” American kitchen, featuring an electric stove, a refrigerator, and a dishwasher.  Khruschev said the Soviet Union produced similar products; Nixon barbed  back that even Communist Party leaders didn’t have such things in their homes, typically, but such appliances were within the reach of every American family.  It was the “Kitchen Debate.”

Try explaining this to high school U.S. history students.  The textbooks tend to avoid this story, because it stops the class.  That’s a sign it should be used more, I think.  Does the Common Core even touch it?

Nixon’s arrival as a major political force in the Cold War grew clear from this event.  The pragmatic stakes of the Cold War were drawn in stark contrast, too.  It’s interesting to ponder that microwave ovens were not part of the exhibit.

Cover of Time Magazine, July 22, 1974, explaining the showdown between President Richard Nixon and the Special Prosecutor, playing out in the U.S. Supreme Court. Image copyright by Time Magazine.

July 24, 1974: In U.S. vs. Nixon, The U.S. Supreme Court ruled unanimously that President Richard Nixon had to turn over previously-secret recordings made of conversations in the White House between Nixon and his aides, to the special prosecutor appointed to investigate the Watergate affair and cover-up.  Nixon would resign the presidency within two weeks, the only president to leave office by resignation.

July 24, 1975: An Apollo spacecraft splashed down after a mission that included the first link-up of American and Soviet spacecraft.  (The Apollo mission was not officially numbered, but is sometimes called “Apollo 18″ — after Apollo 17, the last trip to the Moon.)

Humanity’s hope for the future: A giant leap for mankind on July 20, 1969

July 20, 2013

It’s a day to remember history.  Do you remember that day, the first time humans set foot on the Moon?

(This is based on an earlier post.)

Southwest Elementary in Burley, Idaho, existed in a world far, far away from the U.S. space program. We watched rocket launches on black and white televisions — the orbital launches were important enough my father let me stay home from school to watch, but when he dropped me off at school, I was in a tiny band of students who actually made it to school. Potato farmers and the merchants who supported them thought the space program was big, big stuff.

By John Glenn’s flight, a three-orbit extravaganza on February 20, 1962, a television would appear in the main vestibule of the school, or in the auditorium, and we’d all watch. There were very few spitballs. Later that year my family moved to Pleasant Grove, Utah.

Toward the end of the Gemini series, television news networks stopped providing constant coverage. The launch, the splashdown, a space walk or other mission highlight, but the nation didn’t hold its breath so much for every minute of every mission. Barry McGuire would sing about leaving the planet for four days in space (” . . . but when you return, it’s the same old place.”), then six days, but it was just newspaper headlines.

The Apollo 1 fire grabbed the nation’s attention again. Gus Grissom, one of the three who died, was one of the original space titans; death was always a possibility, but the U.S. program had been so lucky. Apollo’s start with tragedy put it back in the headlines.

The space program and its many successes made Americans hopeful, even in that dark decade when the Vietnam War showed the bloody possibilities of the Cold War. That darkest year of 1968 — see the box below — closed nicely with Apollo 8 orbiting the Moon, and the famous Christmas Eve telecast from the three astronauts, Frank Borman, Jim Lovell, and William A. Anders. The space program kept us hopeful.

By early 1969 many of us looked forward to the flight of Apollo 11 schedule for July — the space flight that promised to put people on the Moon for the first time in history, the realization of centuries-old dreams.

But, then I got my assignment for Scouting for the summer — out of nearly 50 nights under the stars, one of the days would include the day of the space walk. Not only was it difficult to get televisions into Maple Dell Scout Camp, a good signal would be virtually impossible. I went to bed knowing the next day I’d miss the chance of a lifetime, to watch the first moon landing and walk.

Just after midnight my sister Annette woke me up. NASA had decided to do the first walk on the Moon shortly after touchdown, at an ungodly hour. I’d be unrested to check Scouts in, but I’d have seen history.

And so it was that on July 20, 1969, Neil Armstrong became the first human to set foot on the Moon: “A small step for a man, a giant leap for mankind,” was what he meant to say in a transmission that was famously garbled (at least he didn’t say anything about jelly doughnuts).

P. Z. Myers says he remembers a lawnmower going somewhere. It must have been very bright in Seattle. (Thanks for the reminder, P.Z., and a tip of the old scrub brush to you.)

2013 will mark the 44th anniversary.

Texas Essential Knowledge and Skills (TEKS) lists 11 dates for U.S. history as the touchstones kids need to have: 1609, the founding of Jamestown; 1776, the Declaration of Independence; 1787, the Constitutional Convention; 1803, the Louisiana Purchase; 1861-1865, the American Civil War; 1877, the end of Reconstruction; 1898, the Spanish American War; 1914-1918, World War I; 1929, the Stock Market Crash and beginning of the Great Depression; 1941-1945, World War II; 1957, the launching of Sputnik by the Soviets. Most teachers add the end of the Cold War, 1981; I usually include Apollo 11 — I think that when space exploration is viewed from a century in the future, manned exploration will be counted greater milestone than orbiting a satellite; my only hesitance on making such a judgment is the utter rejection of such manned exploration after Apollo, which will be posed as a great mystery to future high school students, I think.)

* 1968, in roughly chronological order, produced a series of disasters that would depress the most hopeful of people, including: the Pueblo incident, the B-52 crash in Greenland, the Tet Offensive in Vietnam, the nerve gas leak at the Army’s facility at Dugway, Utah, that killed thousands of sheep, Lyndon Johnson’s pullout from the presidential race with gathering gloom about Vietnam, the Memphis garbage strike, the assassination of Martin Luther King, Jr., riots, the Black Panther shoot out in Oakland, the Columbia University student takeover, the French student strikes, the tornadoes in Iowa and Arkansas on May 15, the Catonsville 9 vandalism of the Selective Service office, the sinking of the submarine U.S.S. Scorpion with all hands, the shooting of Andy Warhol, the assassination of Robert F. Kennedy, the Buenos Aires soccer riot that killed 74 people, the Glenville shoot out in Cleveland, the cynicism of the Republicans and the nomination of Richard Nixon and Spiro Agnew, the Warsaw Pact invasion of Czechoslovakia crushing the “Prague Spring” democratic reforms, the Chicago Democratic Convention and the police riot, the brutal election campaign, the Tlatololco massacre of students in Mexico City, Black Power demonstrations by winning U.S. athletes at the Mexico City Olympics, coup d’etat in Panama. Whew!

May 25, 1961, 52 years ago: John Kennedy challenged America to go to the Moon

May 26, 2013

President Kennedy at Congress, May 25, 1961

President John F. Kennedy speaking to a special joint session of Congress, on May 25, 1961; in this speech, Kennedy made his famous statement asking the nation to pledge to put a man on the Moon and bring him back safely, in the next ten years.

It was an era when Congress would respond when the President challenged America to be great, and Congress would respond positively.

On May 25, 1961, President Kennedy delivered a special message to Congress, on the challenges facing the U.S. around the world, in continuing to build free market economies, and continuing to advance in science, as means of promoting America’s future.  He closed with the words that have become so famous.  From the Apollo 11 Channel, excerpts from the speech, via Fox Movietone news:

History from the Apollo 11 Channel:

In an address to a Joint session of the United States Congress, Kennedy announces full presidential support for the goal to “commit…before this decade is out, to landing a man on the Moon and returning him safely to the Earth” and urges Congress to appropriate the necessary funds, eventually consuming the largest financial expenditure of any nation in peacetime.

Though Kennedy had initially been convinced that NASA should attempt a manned mission to Mars, NASA Associate Administrator Robert Seamans spent three days and nights working, ultimately successfully, to convince him otherwise.

The complete speech is 46 minutes long.  The JFK Library has a longer excerpt in good video I haven’t figured out how to embed here, but it’s worth your look.  The Library also features the entire speech in audio format.

The complete copy of the written text that President Kennedy spoke from, is also available at the JFK Library.

NASA has a good site with solid history in very short form, and links to a half-dozen great sites.

Can you imagine a president making such a challenge today?
